Structural Mechanics Simulation Failure (Imported Displacements)
Hi everyone! I am currently trying to run a 3D transient structural simulation using ANSYS Mechanical, but I am running into a few problems.
Here is my scenario (see picture below for more detail):
I have a section of myocardium (body1, flexible) with an implanted cannula (body2, rigid). I also manually defined the contact between the two bodies as a joint; please note that the contact is simply an edge (circle). I imported a displacement load from a .txt. with xyz displacements that map correctly to the named selection (i.e. nodal selection of the myocardium wall). This displacement load is set for 0.03s into the simulation.
The goal: I want to see how the cannula moves (in terms of translation/angle/rotation) as the myocardium deforms.
However, when I run the simulation, it almost immediately crashes. I am not sure what I am doing wrong, but any advice would help!
